. IMPROVEMENT IN PILL-MACHINES.

Specification forming part of Letters Patent- N0.Il7,865, dated July 28 1-.57.

To all whom it may concern:

Be it known that I, JAMES C. AYER, of Lowcell, in thecouuty of Middlesex and Common- .wealth of Massachusetts, have invented a novel tion ouline A B, Fig. 1. Fig. 4 denotes one end elevation; Fig. 5, the opposite end elevation; Fig. 6,'the end view of the forming cylinders -for forming the globules.

The nature of my invention consists infirst forming semi-solid material of which the globules areto be madein circularrods by compressing this material with great force, in the manner hereinafter seen, through a strong cyl- 'in'der; and then forming globules of these rods by means of two corrugated cylinders, one of which is revolved at greater speedlthan the I construct a frame of wood, (seen at A in Figs. 1, 2, 3, 4, and 5 of the accompanying drawings,) to which I suspend a driving-shaft, B, so as to freely revolve. One of the cylinders for forming the globules (seen at F,Figs. 1 and 4) is secured near to the end of this driveshaft B, while a gear (seen at R, Figs. land 4) is securedto' its end, and which gears into and turns an intermediate gear, U, .Figs. 1, 2, and 4, and this gears into and turns the other globule -.cylinder, G, Figs. 1, 2, 3, and 4, with greater speed than the cylinder F, and in the same direction. The, intermediate gear, U, turns freely on the stud a, Fig. 4, while the gear S and cylinder G are driven by it.- The periphery of both the cylinders F and G are grooved, as seen in the drawings at Figs. 1 and 2, and are placed side by side for operation'when in the machine, as seen at Figs. 1 and 4, so that the edges left, by forming these grooves will quite touch each other, thusleaving round holes down between each of these edges when these cylinders are so laid together.

I construct a hollow cylinder (seen at- H, Figs. 1, 2, 3, and 4) and place it in the stands B Figs. 1, 2, and3, and to the inside of which cylinder is fitted a plunger, so as tornove tight therein, as seen at-A, Figs'l, 2, and 3. This plunger is fastened to the forward end of a.

screw, K, Figs. 1, 2, and ,3, which passes through and is driven by the hub of the gear D, revolvedin the stands'W, Figs. 1, 2, 3, and 5, which gear-hub forms the not for this screw, which is prevented from turning by the pin L, Figs. 2, 3,v and 5,..withone of its ends in the groove GI, Figs. 1, 3, and 5, and, by turning of this gear D by the pinion O on the drive-shaft B, will drive the screw Kand plunger Aforward into the cylinder H with great force and press out the semi-solid'substance out of the end or small hole e of the cylinder H, which, when so pressed out in the form of round rods, will be cut or severed by the knife F, which is hoisted up'and thrown forward by -the cam M, which is fixed to the apron-shaft N' and forced to quickly drop and sever the rod D, Fig. 4, and-then move back out of the way'of the rod by the spring -V, ready to be again raised and pushed forward ready to again out the rod D- by the cam M, revolved on the shaftN, which revolves in the boxes X, in con nection with the spring V. Anotheraprom shaft (seen at Q) is fittedto the boxes Y, Fig. 1 ,ar0und both of which the apron I is revolved over the pulleys T by means of the band P, Figs. 1, 2, and '4, which is driven by the main shaftB, and thence passing around the pulley O onthe apron-shaft N, which pulleys T are fastened to these apron shafts. The object of this apron is to conduct the rods D" of semi solid substance along on its upper surface as it is driven through the cylinder until it is out off by the dropping of the knife -F. Then the rod D is dropped down by hand between the cylinders Fand G, as they are revolving one faster than the other, and by which the whole rod D is instantly formed into globules and deposited under the machine,'as seen at c, Fig. 2, and so onuntil the contents 0" in the cylinder H are exhausted. The globe form is be again operated upon. If pills are to be made, the composition or ingredients of which they are to be composed should be thoroughly mixed, after whichit is placed in the cylinder H, and then operated upon, as before'mentioned-'-that is, the whole machine being put in operation, the material C will be pressed through the hole 6. in the cylinder H in the form of a wire or round rod and cut-off at {proper lengths to be formed into globules or pills when dropped between the cylinders F and G as they are in motion.

At Fig. 6 is a view of the end of bothcylinders F and G, with a pill-rod, D,'dropped between them,. ust ready for the pilling oper ation to commence, as will be readily understood. A balance-wheel (seen at J, Figs. 1,

2, 4, and 5) is secured to-t-he main shaft B, to which power from any known motor can be applied to drive my machine. This description of construction so embodies the'machines operation that no further description on that point is deemed necessary.

1. The corrugated or grooved globule-cylinders F and G, or their equivalents, for forming the rods of mass or semi-solid material into globules, when constructed, arranged,and

operated essentially in the manner and for the purposes fully set forth.

2. The cylinder H, plunger A, and screw K, for forming the round rods D of the desired size, arranged and operated substantially in the manner and for the purposes fully set tenth.

3. The knife F, or its equivalent, for cutting the rods D of semi-solid substance the desired length, so arranged, as Within specified, that it-will cut or sever the rods D without its sticking to them,.essentially in the manner and forthe purposes fully set forth.
